Bariatric surgery denials
Sleeve gastrectomy, gastric bypass, and revision surgery are denied for unmet criteria far more often than for medical reasons: BMI history, a supervised weight-loss program, a psychological evaluation, or nutrition counseling missing from the file.
What gets denied
- Sleeve gastrectomy or Roux-en-Y gastric bypass
- Revision or conversion surgery after weight regain or complications
- Surgery for patients with BMI between 35 and 40
- Adolescent bariatric surgery
- Surgery when the plan has a bariatric exclusion
Common denial reasons
- BMI history not documented over the period the policy requires
- Supervised weight-loss program not completed or not documented month by month
- Psychological evaluation or nutrition consult missing
- Comorbidity not documented in the record
- Plan excludes weight-loss surgery as a benefit
How we approach the appeal
Request the plan's bariatric policy. Assemble the BMI history from every visit, the dated notes from the supervised program, the psychological evaluation, and the nutrition assessment, and index them to each criterion. If the denial is a benefit exclusion, check the plan document; an exclusion is appealed on the plan language, not on medical necessity, and external review may not be available. For revision surgery, document the complication or the anatomic failure, since criteria differ from first surgery.
Internal appeal: at least 180 days to file for commercial and employer plans; pre-service decisions within 30 days (29 CFR 2560.503-1). Medicare Advantage: 65 days to request reconsideration. External review within 4 months of the final internal denial for ACA-covered plans.
Bariatric procedures are high-cost hospital surgeries; the amount at stake is the plan's allowed amount for the surgery and the hospital stay.
